WASHINGTON - President Obama is looking to tap San Antonio Mayor Julian Castro to head the department of Housing and Urban Development, The New York Times and CNN reported Saturday.

Current HUD Secretary Shaun Donovan would then slide over to lead the White House Office of Management and Budget. Obama has nominated former OMB chief Sylvia Mathews Burwell to take over as secretary of Health and Human Services.

White House spokesman Eric Schultz declined Saturday to provide any information about the reported Cabinet shuffle.

"We have no personnel announcements at this time," he said.

The moves are part of a domino effect following the resignation last month of Kathleen Sebelius, who left after the troubled rollout of HealthCare.gov. Her departure allows the president to shake things up in his Cabinet for the final two years of his term.

Castro, 39, is a three-term mayor who has been widely talked about for higher office. He is considered an up-and-coming star in the Democratic Party, and his speech at the 2012 Democratic National Convention only served to burnish his reputation.

Donovan has led HUD since just days after Obama took office. Obama tapped him to lead a task force in the wake of Superstorm Sandy. After the president won re-election, Donovan was the subject of much speculation about what the second-term Cabinet would look like and how long he would stay.
